RNA interference

noun

: a posttranscriptional genetic mechanism of eukaryotes that suppresses gene expression and in which double-stranded RNA cleaved into small fragments initiates the degradation of a complementary messenger RNA sequence
also : a technique (such as the introduction of double-stranded RNA into an organism) that artificially induces RNA interference and is used for studying or regulating gene expression
